Important: The PCM Idle Learn Procedure must be performed whenever the battery is disconnected. Refer to Crankshaft Position System Variation Learn . Perform the CKP System Variation Learn Procedure when the Crankshaft Position sensor is removed or replaced.

1. Remove the starter. Refer to Starter Motor Replacement in Engine Electrical.



2. Disconnect the Crankshaft Position (CKP) sensor electrical connector.



3. Remove the CKP sensor retaining bolt.
4. Remove the CKP sensor.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

1. Install the CKP sensor.



2. Install the CKP sensor retaining bolt.
